All Known Implementing Classes:

DefaultSystemUserAgent
```
@ThreadSafe
public interface SystemUserAgent
```
Common system level user agent properties that can either be accessed as a string or as individual values. The former is useful when making generic calls, for instance to local endpoints when resolving identity, while the latter is when incorporating this information into a user agent header in an SDK request.
